Description

Technical Field

[0001] The utility model belongs to the field of water pump controllers, in particular to a water pump controller. Background Art

[0002] Existing water pumps are usually used in situations where water is pumped or drained. It is inevitable that water will splash onto the surface of the controller during use. Therefore, the waterproof structure of the controller is particularly important. Usually, the water controller includes an upper cover and a bottom box, which are directly enclosed together. Waterproof glue or a waterproof gasket is provided at the connection between the upper cover and the bottom box. When routing the controller, in order not to damage the waterproof glue or the waterproof gasket, a wire outlet hole is usually provided on the side or bottom of the controller. In particular, a waterproof component (such as a rubber ring, etc.) is required at the wire outlet hole on the side to fix the wires led out of the circuit board and form a waterproof structure. The additional waterproof component protrudes from the controller, increasing the probability of accidental contact. In addition, if the waterproof component is not firmly matched, it is easy to fall off under external force collision, and the structure is not reliable. Utility Model Content

[0003] In view of the problem of unreasonable wiring structure setting of existing controllers, the utility model provides a controller for a water pump, which forms a wiring space for connecting wires by arranging a surrounding edge on the upper cover and spacing it with the side wall of the bottom box, and covers the lead-out part of the connecting wires to effectively prevent accidental contact.

[0004] The utility model adopts the following technical solution: a controller for a water pump, comprising an upper cover and a bottom box that can cooperate with each other, a circuit board is arranged in the space enclosed by the upper cover and the bottom box, the circuit board is connected with a connecting line used as a communication line or a power line, the bottom box has a side wall, the upper cover is provided with a peripheral edge extending downward, a gap is arranged between the peripheral edge and the side wall, and the connecting line can extend from the gap.

[0005] The upper cover has a surrounding edge, which is spaced apart from the side wall of the bottom box. The connecting wires of the circuit board extend out from the space, and the lead-out parts of the connecting wires are covered, thereby effectively preventing accidental contact.

[0006] Furthermore, the upper cover is provided with a waterproof wall, the waterproof wall is located inside the surrounding edge and is spaced apart from the surrounding edge; the top of the side wall is provided with a waterproof step, the lower end of the waterproof wall can cooperate with the waterproof step to form a waterproof structure. The surrounding edge is located outside the waterproof wall, forming a first waterproof structure, and the waterproof wall and the waterproof step cooperate to form a second waterproof structure, and the two waterproof structures effectively protect the circuit board.

[0007] Furthermore, a wiring hole is provided on the waterproof wall, and the wiring hole is close to the top of the upper cover. The wiring hole can connect the cavity surrounded by the waterproof wall with the cavity surrounded by the surrounding edge, so as to facilitate wiring.

[0008] Furthermore, a plurality of support ribs are provided at intervals between the waterproof wall and the surrounding edge, and the support ribs ensure the connection strength between the waterproof wall and the surrounding edge, and prevent the surrounding edge from sinking inwards under the action of external force.

[0009] Furthermore, reinforcing ribs are provided between the waterproof wall and the surrounding edge, and the reinforcing ribs form a reinforced area around the wiring hole. Providing a wiring hole on the waterproof wall will cause certain damage to the strength of the waterproof wall. The provision of reinforcing ribs can form a reinforced protection structure around the wiring hole to avoid destructive damage to the waterproof wall when the connecting line is pulled.

[0010] Furthermore, the upper cover is provided with a hollow column, the hollow column is connected to the waterproof wall and is located outside the waterproof wall, the bottom box is provided with a connecting column, the connecting column is located outside the waterproof step, and a connector is connected to the hollow column and the connecting column to connect the upper cover and the bottom box. The connection between the upper cover and the bottom box depends on the connector. If the connector is arranged inside the waterproof structure, the water accumulated on the surface of the connector will enter the circuit board, which may cause a short circuit. Therefore, the hollow column and the connecting column used to support the connector are located outside the area surrounded by the waterproof wall and the waterproof step.

[0011] Furthermore, the outer side of the surrounding edge is concave to form a clearance area. A water pump usually has a motor, a pump body driven by the motor, a pressure tank connected to the pump body, and a controller arranged on the motor. Generally speaking, the assembly order of the controller and the motor is prioritized, and the assembly order of the connecting components at the water outlet and the water inlet of the pump body is relatively late. If a three-way valve or a five-way valve is threadedly connected at the water outlet of the pump body, the three-way valve or the five-way valve may collide with the controller during the assembly process. The provision of the clearance area can effectively reduce the probability of collision while achieving a compact structure.

[0012] Furthermore, a heat sink is provided on the outer side of the bottom box, the heat sink forms a heat dissipation area, and a heat conduction step is provided on the inner side of the bottom box, and the vertical projection of the heat conduction step falls into the heat dissipation area.

The circuit board is connected to the support column, and the height of the support column is lower than the connecting column, so that the circuit board can be accommodated in the bottom box, so that the center of gravity of the entire controller is lower and the internal space layout of the controller is more reasonable.

[0014] The utility model has beneficial effects: the present application is a controller for a water pump, which includes an upper cover and a bottom box, a circuit board is arranged between the upper cover and the bottom box, and the upper cover has a surrounding edge, which is spaced apart from the side wall of the bottom box, the connecting wires of the circuit board extend from the space, and the lead-out part of the connecting wires is covered, which effectively prevents accidental contact.

DETAILED DESCRIPTION

[0020] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the utility model, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0021] The water pump controller of this embodiment, as shown in the figure, includes an upper cover 1 and a bottom box 2 that can cooperate with each other. A circuit board 3 is provided in the space enclosed by the upper cover 1 and the bottom box 2. The circuit board 3 is connected to a connecting line used as a communication line or a power line.

A gap A is provided between the peripheral edge 11 and the side wall 21, and the connecting line can extend from the gap A.

[0022] The upper cover 1 has a peripheral edge 11, which is spaced apart from the side wall 21 of the bottom box 2. The connecting wires of the circuit board 3 extend out from the space A, and the lead-out portion of the connecting wires is covered, thereby effectively preventing accidental contact.

[0023] The upper cover 1 is provided with a waterproof wall 12, which is located inside the surrounding edge 11 and spaced apart from the surrounding edge 11; a waterproof step 211 is provided on the top of the side wall 21, and the lower end of the waterproof wall 12 can cooperate with the waterproof step 211 to form a waterproof structure. The surrounding edge 11 is located outside the waterproof wall 12 to form a first waterproof structure, and the waterproof wall 12 cooperates with the waterproof step 211 to form a second waterproof structure, and the two waterproof structures effectively protect the circuit board 3.

[0024] The waterproof wall 12 is provided with a wiring hole 121, and the wiring hole 121 is close to the top of the upper cover 1. The wiring hole 121 can connect the cavity surrounded by the waterproof wall 12 with the cavity surrounded by the surrounding edge 11, so as to facilitate wiring.

[0025] A plurality of spaced support ribs 13 are provided between the waterproof wall 12 and the surrounding edge 11. The support ribs 13 ensure the connection strength between the waterproof wall 12 and the surrounding edge 11, and prevent the surrounding edge 11 from sinking inwards under the action of external force.

[0026] Reinforcing ribs 14 are further provided between the waterproof wall 12 and the surrounding edge 11, and the reinforcing ribs 14 form a reinforced area around the wiring hole 121. Providing the wiring hole 121 on the waterproof wall 12 will cause certain damage to the strength of the waterproof wall 12. The provision of the reinforcing ribs 14 can form a reinforced protection structure around the wiring hole 121 to avoid destructive damage to the waterproof wall 12 when the connecting line is pulled.

[0027] The upper cover 1 is provided with a hollow column 15, which is connected to the waterproof wall 12 and is located outside the waterproof wall 12. The bottom box 2 is provided with a connecting column 22, which is located outside the waterproof step 211. The connecting piece is connected to the hollow column 15 and the connecting column 22 to connect the upper cover 1 and the bottom box 2. The connection between the upper cover 1 and the bottom box 2 depends on the connecting piece. If the connecting piece is set inside the waterproof structure, the water accumulated on the surface of the connecting piece will enter the circuit board 3, which may cause a short circuit risk. Therefore, the hollow column 15 and the connecting column 22 used to support the connecting piece are located outside the area surrounded by the waterproof wall 12 and the waterproof step 211.

[0028] The bottom box 2 is provided with a support column 23, which is used to support and connect the circuit board 3, and the height of the support column 23 is lower than the connecting column 22. The circuit board 3 is connected to the support column 23, and the height of the support column 23 is lower than the connecting column 22, so that the circuit board 3 can be accommodated in the bottom box 2, so that the center of gravity of the entire controller is lower and the internal space layout of the controller is more reasonable. The circuit board 3 is provided with a capacitor 31, and the capacitor 31 is located on the upper surface of the circuit board 3.

[0029] The outer side of the surrounding edge 11 is concave to form a clearance area 16. A water pump usually has a motor, a pump body driven by the motor, a pressure tank connected to the pump body, and a controller arranged on the motor. Generally speaking, the assembly order of the controller and the motor is priority, and the assembly order of the connecting components at the water outlet and the water inlet of the pump body is relatively late. If a three-way valve or a five-way valve is threadedly connected at the water outlet of the pump body, the three-way valve or the five-way valve may collide with the controller during the assembly process. The provision of the clearance area 16 can effectively reduce the probability of collision under the premise of compact structure.
